Two bodies of masses 2 m and m have their K.E. in the ratio 8 : 1, then their ratio of momenta is

A

`1:1`

B

`2:1`

C

`4:1`

D

`8:1`

Text Solution

Verified by Experts

The correct Answer is:
C

`P =sqrt(2mK)`
`P_1/P_2=sqrt((2m_1K1)/(2m_2K_2))=sqrt((2m xx 8)/(mxx1))=4`
`implies P_1 =4P_2`

Relation between kinetic energy and momentum Let us consider a body of mass 'm' having a velocity 'v', then momentum of the body P = mass xx velocity P = m xx v rArr v = (P)/(m) " "...(1) From definition, kinetic energy (K.E) of the body K.E = (1)/(2) mv^(2)" "...(2) Now putting the value of (1) in (2) we have K.E = (1)/(2)m ((P)/(m))^(2) K.E. = (1)/(2)m (P^(2))/(m^(2)) = (1)/(2) (P^(2))/(m) = (P^(2))/(2m)" "...(3) Thus we can write P^(2) = 2m xx K.E rArr P = sqrt(2m xx K.E) Thus momentum = sqrt(2 xx "mass" xx "kinetic energy") Two bodies masses 1 kg and 4 kg having equal kinetic energies.
